Title: Multiple verification system for digital signature
Inventor: OTA KAZUO
IPC: G06F21/40
Filed: 1991-02-19
Abstract: PURPOSE:To provide the multiple verification system for the digital signature which performs efficient approval and rejection without repeating a procedure as many times as verifies when the verifies verify the signature on a document that a signer signs. CONSTITUTION:When the verifies verify whether or not the signature of a message that the signature 200 signs is legal, the signer 200 prepares a communication sentence regarding the signature by using the open information at the center 100 and sends it to a next verifier 300. Consequently, the communication sentence wherein the signer 200 confirms or rejects the signature is passed from the starting verifier 300 to a final verifier 800 while upsetting with random numbers, so an inspecting process need not be repeated as many times as the verifiers.
